Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the number of the connectors 1 is 3, and the included angles of two adjacent connectors 1 are uniformly distributed at 120 degrees and are arranged on a machine tool disc. The connector 1 is of a cuboid structure, and two positioning mounting holes are formed in the connector and used for being fixedly mounted on a machine tool. The lower part of the connector 1 is connected with a machine tool, the upper part of the connector 1 is connected with the movable body 2, the movable body 2 is V-shaped, the V-shaped intersection of the movable body 2 is connected to the connector 1 through the movable shaft 4, and the movable body 2 can rotate around the movable shaft 4 relative to the connector 1. Two clamping jaws 3 of both ends fixed mounting of activity body 2, the rectangular block of clamping jaw 3 lower part is fixed in the clamping jaw mounting groove 23 of activity body 2 through clamping jaw fastening

bolt

6, and 3 upper portions of clamping jaw are the cylinder, and the cylinder processing has right angle draw-in groove 31, and the cell body inner wall and the work piece contact of right angle draw-in groove 31 are used for the centre gripping work piece. The clamping jaw 3 is a replaceable part and is matched with clamping jaws 3 with different sizes according to the size of a clamped workpiece. When the clamping jaw 3 is used and worn excessively, the clamping jaw 3 can be directly replaced, so that the production cost can be saved.

As shown in fig. 1, the movable body 2 and the connection body 1 are fixed to each other with their center lines being overlapped with each other by two fixing pins 5 between the connection body 1 and the movable body 2. The initial position of the clamp is kept stable, and the clamp is convenient to mount.

As shown in fig. 2 and 3, two positioning blocks 21 parallel to the length direction of the connecting body 1 are processed on two sides of the connecting body 1 on the side of the movable body 2 facing the connecting body, the positioning blocks 21 are spaced from the connecting body 1, a movable groove 22 is formed between the two positioning blocks 21, the contact surface between the connecting body 1 and the movable body 2 is located in the movable groove 22, and the positioning blocks 21 limit the rotation range of the movable body 2, so that the movable body 2 is limited in the movable groove 22 around the movable shaft 4 relative to the connecting body 1. The maximum rotation amplitude of the movable body 2 around the movable shaft 4 is that one side of the connecting body 1 is pressed against the positioning block 21. The structure prevents the clamp from being installed on a machine tool disc, the movable body 2 is prevented from rotating excessively downwards due to the action of gravity, the amplitude of the movable body 2 needs to be adjusted manually by a worker when a workpiece is clamped, the movable body is not convenient to adjust greatly, and the labor intensity of the worker is increased.

When the fixture is used, the three groups of fixtures are installed on a machine tool disc, and the positions of the fixtures are adjusted and fixed according to the diameter of a workpiece to be processed; then the fixing pin 5 is pulled out, the workpiece is clamped on the clamping jaws 3 of the clamp, and the right-angle clamping grooves 31 of the 6 clamping jaws 3 are kept in contact with the workpiece; then starting the machine tool to process the workpiece, automatically aligning the movable body 2 along with the rotation of the machine tool around the movable shaft 4 to keep the workpiece at the clamping side of the clamp in the original shape without extrusion deformation, and forming the processed side into a standard circle in one step after processing according to the program of the machine tool. And after one side is machined, the workpiece is turned over and then clamped on the clamp to machine the other side. After the workpiece is disassembled, each movable body 2 can be positioned through one fixing pin 5, and the workpiece can be clamped for the second time conveniently.

The workpiece can be processed and finished through twice processing without repeated processing, the production efficiency and the qualification rate of products are effectively improved, and the labor intensity of workers is greatly reduced.

The above is the utility model discloses a concrete embodiment and the technical principle who utilizes, any basis the utility model discloses any modification, equivalent transformation on the technical scheme basis all should be contained within the protection scope.
